Packers see set at OG right now. OT is were they could use depth but it seemed the OT depth was not really great this draft. Does GB really need to add more project OTs?
Actually, I'd argue somewhat the opposite. You have lots of developmental depth at OT, it's a future starter we lack - IMO. The depth problem is at C/G. Sure, you are good with Jenkins and Runyan as starters but Myers is so far a draft miss and isn't solid at all.
The back-ups inside are Jake Hanson and Royce Newman who aren't very good, and Sean Rhyan who has showed nothing. Unless you feel they should move Zach Tom inside (which I wouldn't mind, but it seems like the team likes him at OT) they've got almost nothing for quality depth inside, and I'd argue are short 1 starter inside.
I would like to have seen them take a G/T option somewhere late, but maybe there just wasn't a guy they really liked.
